Take extended time lapse videos from hours to days. Allows you to specify time interval and playback rate. Runs on older iPhones that do not have a time lapse option as part of the built in camera app. Saves videos in camera roll.
Fault tolerant design saves individual frames during image capture. Frames are assembled into a video as a separate step. This insures successful creation of a video should the device run out of power.
Latest version stores geo-coordinates for playing back time lapse movie with map display.
